'LEVIHUSSER OF NEW YORK, N. Y., ASSIGNOR TO THE MINING AND DREDGING POWER COMPANY, OF WEST VIRGINIA.

STEAM vAouUn/i-DRF.Des'` SPECIFICATION forming part of Letters Patent No. 526,529, dated September 25, 1894.

Application filed September 2, 1892. Renewed March 30, 1894. Serial No. 505,779. (No model.)

To afZZ whom it may concerns' Be it known that I, LEVI I'IUSSEY, a citizen of the United States, and a resident of New' York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Steam Vacuum- Dredges, of which the following is a specifishowing the same arranged on a barge. Fig.

2 is a side elevation of the same. Fig. 3 is a vertical transverse section, on the line 3 3, Fig. l, on an enlarged scale.

Similar letters of reference indicate correspending parts.

Referring to the drawings, A represents a barge or vessel which is moored in a suitable manner to the place where the dredging operation is to be performed.

The derrick B is arranged at one end of the barge, and supports the grappling fork or bucket C by which the material is taken up from the bottom, and then transferred to a tank D that is arranged on the center of the barge, or if the material is not small enough but consists of larger lumps and pieces to a comminuting apparatus E that is arranged at the side of the tank on the deck of the barge and connected by an inclined chute F with the tank D. The comminuting apparatus consists of rollers G having pointed teeth Gr the rollers being arranged near enough together so that the material conveyed to the same is broken up and comminuted f the opposite end of the barge. The grappling fork is also operated by a suitable hoisting engine in the usual manner in barges of this kind. Both the tank D and the rollers of the comminuting apparatus are supplied with water by means of pipes f f through which water is supplied by a pump J. This water serves to lubricate and partly dissolve the material supplied by the grappling fork and the rollers break it up and mix it with the water and thus prevent clogging of the suction pipe. Y

At one side of the tank D is arranged a vacuum pump K the suction pipe L of which terminates near the bott-om of the tank D. The vacuum pump is provided with gate Valves which are operated by steam cylinders. The comminuted and liquefied material is taken up by the suction pipe L and con# ducted through the discharge pipe M, which is composed of a number ef jointed pieces that are supported in floats O and extended to the point of deposit for theexcavated material.

My improved steam dredge can be used to great advantage in increasing the depth of lakes, reservoirs, slips, or for deepening a. channel of a river or other water course, cutting canals and the like, as the material is readily transferred from the point of excavation, to the barge and from the barge to the place of deposit, whereby a quick, effect- Vive and comparatively inexpensive dredging operation is obtained, and is of special serv-h ice Where hard earth is to be delivered a long` LEVI HUSSEY.
